I have been getting some calls for aeration and topdressing. did a few jobs this past fall and am looking into getting equipment to do this more efficiently. most of the areas I will doing are larger and generally on a slope. I am looking at tow behind units for topdressing and aerating. considering an aerator to run on a small tractor 3 point and then tow a topdresser with the same tractor. i have found good prices on used turfco and other brand topdressers, any suggetstions for a good aerator. i have been thinking about the aerovator from 1st products. any comments or suggestions would be appreciated.
